This invention relates to road culverts audit isanj object-fof lthe invention to provide a device of this kind constructed in a manner whereby the various parts embodied in its structure may be readily assembled and effectively maintained in desired assemblage.

Furthermore, it is an object of the invention to provide a device of this kind comprising a removable top structure together with means whereby such top structure may be conveniently applied to and effectively maintained in working position.

The invention consists in the details of l5 construction and in the combination and arrangement of the several parts of my improved road culvert whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a vertical sectional view taken 3o lengthwise through a culvert constructed in accordance with an embodiment of my invention;

Figure 2 is a sectional view taken substantially on the line 2--2 of Figure 3;

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1;

Figure 4 is a sectional view taken substantially on the line 4-4 of Figure 1;

Figure 5 is a view in perspective of a top wall section unapplied;

Figure 6 is an end elevational view illustrating a slightly modified form of top section.

As disclosed in the accompanying drawings, my improved culvert comprises a plurality of bottom sections 1 arranged end to end and each of said sections is provided along its side or longitudinal marginal portions with upstanding pins 2 which are adapted to extend within the lower edge portions of the side wall sections 3. As is illnstrated in Figures 1 and 2, it is to be noted that the assembly of the side wall sections 3 with respect to the bottom sections 1 is such that the sections 3 lap adjacent the sections 1 thus assuring a rigld structure.

'llheupperA marginalportion of each of thesections -isubstantially midway its ends is provided with a recess 4 While the ends thereof are provided with the notches 5, each of said notches being substantially equal to one-half of a recess 4.

The top of the culvert, as herein disclosed, also comprises a plurality of separable sections 6 each of a length substantially equal to that of a bottom section 1. The under surface of each of the sections 6 closely adjacent to the side marginal portions thereof is provided therealong with the grooves or channels 7 which receive the upper marginal portions of the side walls 3. Each of these grooves or channels 7 substantially midway its ends has its base wall provided with a depending block 8 of a size to snugly engage within va recess provided by a pair of adjacent notches 5, said block 8 having its outer face terminating inwardly of the under face of the section 6 and preferably at a point substantially midway between the base of the groove or channel 7 and the under surface of the section 6. The extremities of the grooveV or channel 7 are provided with depending blocks 9 each of a size equaling that of a notch 5 or a half end portion of a recess 4 sothat when a pair of adjacent top sections 6 are in apkplied'position the adjacent end blocks 9 will snugly engage within a recess 4 as is clearly illustrated in Figure 2 of the accompanying drawings.

The construction ofthe top section 6 is such as to assure a culvert possessing a ymaximum of strength and wherein the several parts may be readily and conveniently assembled.

As indicated in detailed Figure 6, the upper longitudinal margins of each of the sections 6 are beveled, as at 10. This is of advantage under such conditions when the culvert may extend above the surface of the roadway, thus permitting vehicles to readily pass thereover.

From the foregoing description it is thought to be obvious that a road culvert constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modiication without departing from the principles and spirit thereof and for this reason llO I do not wish to be understood as limiting myself to the precise arrangement and `for mation of the several parts herein shown in carrying out my invention in practice eX- cept as hereinafter claimed. Y A

I claimtl A culvert structure comprising a bottom Wall7 side wall panels restingl upon the hottom Wall and provided at their upper edges with recesses, top wall sections provided at their under faces with longitudinally disposed grooves which are spaced from the side edges thereof, said grooves adapted to receive the upper portions of the side panels and top panels being provided with block portions lying in the grooves and which are adapted to enter the recesses of the .side panels.

In testimony whereof I hereunto afiix my signature.

JAMES M. MORGAN.
